CEMENT-WALK-CONSTRUCTING FRAM E.

SPECIFICATION forming part of Letters Patent No. 683,081, datedSeptember 24, 1901.

Application filed January 25, 1901. Serial No. 4,684. (No model.)

To aZZ whom it may concern:

Be it known that I, CORNELIUS J. SULLIVAN, a citizen of the UnitedStates, and a resident of Syracuse, in the county of Onondaga, in theState of New York, have invented new and useful Improvements inCement-Walk- Constructing Frames, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to a frame designed to be used in constructingwalks from plastic cement packed directly upon the ground to-be coveredby the walk.

The object of the invention is to furnish a frame which shall beconveniently adjusted for constructing Walks of different widths anddifferent alinements and shall also be strong and durable for repeateduse; and to that end the invention consists in the novel constructionand combination of the component parts of the frame hereinafterdescribed, and set forth in the claims.

In the accompanying drawings, Figure 1 is a plan View of a frameembodying my invention and showing the same with a walk formed therein.Figs. 2 and 3 are perspective views of opposite end portions of theframe. Fig. 4 is an enlarged perspective view of one end of one of thelongitudinal rails. Fig. 5 is an enlarged vertical longitudinal sectionof the coupled end portions of two longitudinal rails. Fig. 6 is aperspective view of one of the transverse bars. Fig. 7 is a perspectiveview of one end of one of the longitudinal rails provided-With thecoupling-hook. Fig. 8 is a face view of the jointing-knife. Fig. 9 is across-section on line X X in Fig. 8. Fig. 10 is a plan View of myinvention arranged for constructing a curved walk. Fig. 11 is a detachedperspective view of one of the sides of the frame arranged as aforesaid,and Fig. 12 is a detached plan view of a section of the frame designedfor the construction of abrupt turns in the walk.

(ItGt represent the longitudinal rails, and b b the transverse end bars,forming the frame in which the cement walk is to be constructed. Theserails and bars I preferably form of scantlings of suitable dimensionsand embraced by longitudinal metal plates 0 0, ap-

plied to the sides and to the tops and botthe scantlings from warpingand to renderj them strong and durable for repeated use. For firmlyuniting said rails and bars when required for use I rigidly attach toone end of each longitudinal rail or a a metallic block 2, which isprovided with a longitudinal channelfand a lateral channel f, bothterminating in a socketf formed in the block. To the adjacent end of thecompanion rail is rigidly attached a projecting hook g, which isinserted into the channelfand interlocked with one of the walls of thesocket f For connecting the transverse bar b to the rails a a I attachto the ends of said bar hooks g, similar to the hooks q and passingthrough the lateral channels f in the blocks e of the two rails andinterlocking with the side walls of the sockets f The described couplingof the rails and bars by means of the couplinghooks allows the frame tobe readily removed from the completed Walk and to be compactly storedfor subsequent use in the construction of cement walks. 7

For forming abruptly-curved turns in the walk I employcorrespondingly-curved sections 1 of the side rails coupled to the railsa a by means of coupling-hooks interlocking with sockets in metallicblocks attached to the adjacent ends of the parts to be united. Forforming in the walk curves of greater radii than those formed by thesectionsl I employ rail-sections j, coupled to the rails a a, in themanner hereinbefore described and having on their free endslongitudinally-extending flexible steel plates n, which are firmlysecured at one end to the sections j and have their free ends adapted tobe bent to the desired curvature. Said curvature may be determined bymeans of stakes it, driven into the ground at opposite sides of eachplate.

In constructing a Walk the rails a a and bars I) b are to be placed inposition and proper alinement with the walk to be constructed. Then theplastic cement is packed in the frame in the usual manner and leveledeven with the top of the frame by means of a straight-edge placed acrossthe frame and drawn along the top thereof. After this a knife 0 isplaced edgewise transversely upon the surface of the packed cement andforced vertically into said cement to form a joint in the walk. Theknife is thus used at regular intervals in the length of the Walk andremoved therefrom. The walk is subsequently smoothed by means of atrowel, and in this operation the tops of the knife-cuts become filledwith the cement, and thus the aforesaid intended joints are concealed.These joints, however, are subsequently marked and partly reopened bymeans of a suitable edge-tool drawn along a straight-edge placed tocoincide with the aforesaid knife-cut.

Vhat I claim as my invention is- 1.' A cement-walk-constrncting frameconsisting of longitudinal rails spliced detachably end to end and eachof said rails formed with reinforcing vertical and horizontal stayplatesas set forth.

gitudinal metal plates embracing said scant lings, and couplingsdetachably uniting said scantlings as set forth.

5. A cement-walk-constructing frame consisting of scantlings disposedend to end, a metallic block attached to the end of one of saidscantlings and formed with a longitudinal channel extending, from theexterior of the block and terminating in a socket at the interior ofsaid block, and a hook projecting from the end of the adjacent scantlingand interlocking with the aforesaid socket as set forth.

6. A cement-walk-constructing frame c0nsisting of rails and flexibleplates extending longitudinally from the ends of said rails as and forthe purpose set forth.

7. A cement-walk-construeting frame consisting of scantlings, metalplates embracing said scantlings, and flexible plates extendinglongitudinally from the ends of the scantlings as set forth.

8. Acement-walk-constructing frame consisting of longitudinal rails andtransverse bars disposed between said rails, metallic blocks secured tothe ends of the longitudinal rails and provided with lateral channelsterminating in sockets in the interiors of the blocks, andcoupling-hooks projecting from the ends of the transverse bars andinterlocked with the aforesaid sockets as set forth.
